*Math Encounters*: "Space, Time, and the Fourth Dimension" with Robbert Dijkgraaf, Director of Princeton University's Institute for Advanced Study (4:00 pm)

Albert Einstein discovered that time should be seen as a fourth dimension that can be added to the three dimensions of space. What exactly does this mean? Can one imagine higher dimensions? How does geometry work in four-dimensional spacetime? And how does this help us understand fundamental questions in physics like the Big Bang, black holes, and the behavior of elementary particles according to the rules of quantum mechanics?
